ENOS T. HIGHAM, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO HIMSELF AND D. HIGHAM, 0F SAME PLAGE.

WINDOW-SHADE ADJUS'IER.

VSpecification of Letters Patent No.

To all whom t may concern Be it known that I, Enos T. I-IIGHAM, ot Philadelphia, Pennsylvania, have invented an Adjuster for Vindow-Shade Cords; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had' to the accompanying drawing and to the letters of reference marked thereon.

My invention consists of a grooved screw, a nut adapted to the same, a sliding bar and a knob or its equivalent for receiving the cord of the window shade, the whole being arranged and operating as described hereafter, so that the said cord maybe under the control of the screw and nut and cannot become slack without turning the latter.

In order to enable others to makeny invention I will now proceed 'to describe the manner of constructing the same.

On reference to the accompanying drawing which forms a part of this specification, Figure l is a vertical section of my improved adjuster for window shade cords; Fig. Q, a front view of the Same and Fig. 3 a transverse section on the line 1 2, Fig. 1.

Similar letters reiter to similar parts throughout the several views.

A is a screw each end of which is secured to a bent plate B, the two plates being attached to the window frame in a suitable .position by screws or nails passing through 46,650, dated January 24, 1865.

groove for receiving the cord of the window shade being attached to this bar near one end of the same. In place of the knob f a pulley, grooved for the reception of the cord may be hung to a pin attached to the bar e.

A nut /z is adapted to the screw A, incloses the bar c and is confined between the lip z' of the bar and the shoulder 7' formed by the knob, so that on turning the latter thebar e with its knob must be raised or lowered according to the direction in which the nut is turned. a

It will be evident without further description that the device described above affords every facility for tightening or loosening the cord of the window shade, and that the cord being under the control of the screw and nut `cannot become slack without turn- Aing the latter.
